Be it known that I, NsoN B. lVE'ri-Inanx.L,-a citizen of the United States, resichng at Pittsburgh, in the county ot' Allegheny anti State of Pennsylvaniar` have invented certain new and useful improvements in Rail Structures, ot which the followino l is a specification.

This invention relates to rail structures for railroad and street railway traction service and other analogous uses, and it has Jfor its primary objects the provision ot a rail structure which is simple and inexpensive in construction but which has great. strength and lasting wearing qualities and which is easy to assemble and take apart; the provision of a rail structure wherein the use of bolts is dispensed' with; the provisionl of a rail structure which is suhstanf tially continuous in character, that is to say at no point is there a complete break in the rail: the provision of a rail structure of the character specified in which the. parts of the rail aro securely hraeeil against relative Vlateral and vertical displacement` while at the saine time the rail as a whole is sutiieiently springry to prevent hreakages: and in gen eral the provision ot' a rail havingY the characteristics lc-scribed which permits oft the which are'iilnstrateil in the accompanying flra wings, whereinM Figure l is a transverse section through the rail; Figure 2 is a sitle elevation oi the rail shown in AFigure l. ilrawn on a smaller scale: and Figure Il is a transverse section shcm'ing a modification ot the t'orzn shown in Figures 1 ami 3.

ln Fig. l l ha re shown a torni ot my invent-ion. in this torm the rail is rompriseii of two parts, the wel portions lll aiuti respectively carrieil hy the hase and heail ot the rail heini: so constructed as to interlock against: vertical displacement. This accomplished n); prorhlinethe weh Q3 with a hme'ituilinaily extending rih or ino" L5 which fits into a cerresi)willingly shaped reor groove 26 'tormeil in the'weh The heail ot the rail is reccssecl or gioovet'i on either side, ot' the weh portion ivy grooves 27 and 28, the toi-mer of which heing adapted to receive the erige of.' the weh portion The hase ot the rail is groovet adjacent the weh 2S as at T229; i i "-f l noted that the grooves?? is witter the i. than at the top. lin asseinioli the head is held at an angie .ai-r v the base portion anti the enti the weh is brought, into position in the groove l-", after which the weh Q4 is swung toward the ,web 23 until the two ahnt one another in at:

proper coperative relation. This actii made possible hy the Snape oi the fr( As a means for securely inciting' th Y, fof the rail togetlvier, i provide a, hey piate. 30 which is provioleci with a ciownwartlijv depening .lip or flange which tits into the groove 29 anti ahuts the hottoni portion of the weh` 2i anfl ri giaily hohis the two weh portions in proper engagement.. The npper surface of the plate 30 adjacentthe weh is undercuty at 3:2. The key plate is helft in position by means o a plate 253 ie ripper edge of which fits. into the groove 28 "ci, the

lowerportion of which engages the ander out portion of' the hey plate. 'it xviii oit course he understood that. a pluraiity of lier plates are provitleti and preierahiy so ar ranged that their ends ahnt. -The locking; plates are priiwitleii at intl` als as n he neetieti uin ati-.dition to lo( plates, they serve, to brace the ol particular advantage at carries to sap portl the raii against the iaterai thrust ot the wheels on the heat?. of the @no of the primary arrivant @it structure just describen n u that i am enahieii to use a hase I ing' qualities, it; wiil rapidly as .vorrnithfi rail can he repaoed. serveii that ti sterei'h partinin. trateil in lFialres Referring now tiailv like that illustrated irn this t at the top with a nose or i n iiijects within the gri-ocre 26:3, the il laterai thrusts. The

tions oi the plate ahnttii'ig again ot the rail anti serving` to ha@ hase, or similarly extenticci waercoy a desire to secure lows is .provided for the rail. In this construction the plate 30 is of spring metal and is bolted to the metal bed plate 34 which rests upon. a tie in the usualmanner.

Having thus described my invention and key member including a locking member for holding the parts in interlocked position, the key member and head and base portions having interengagin means whereby the key member is locke on movement of the locking member longitudinally of the rail to operative position.

In testimony whereof I have hereunto signed my name in the presence of the two subscribed Witnesses.
